Technetium Tc 99M Sulfur Colloid
Technetium Tc 99m sulfur colloid is a radiolabeled colloidal particle preparation that is phagocytosed by reticuloendothelial cells (Kupffer cells in the liver, spleen, and bone marrow), used for liver-spleen scintigraphy, bone marrow imaging, and sentinel lymph node mapping in breast cancer and melanoma. The particle size determines the biodistribution: larger particles concentrate in the liver and spleen, while filtered smaller particles enable gastrointestinal transit and lymphoscintigraphy. It is widely used for sentinel node biopsy guidance in surgical oncology.
